Can You Use Tile Backer Board Outside Corners

Essential Aspects of Using Tile Backer Board Outside Corners

Tile backer board is an essential material for creating durable and waterproof surfaces in wet areas such as bathrooms and kitchens. It is also commonly used in outdoor applications, such as patios and balconies. However, using tile backer board in outside corners requires special considerations to ensure proper installation and longevity.

One of the key aspects to consider is the type of tile backer board being used. Cement backer boards are the most common type and are suitable for both indoor and outdoor applications. They are highly durable and resistant to moisture, making them ideal for areas that experience heavy water exposure.

Another important aspect is the proper installation of tile backer board in outside corners. This involves using corner beads to create a reinforced and waterproof joint. Corner beads are preformed metal or plastic strips that are installed over the edges of the backer board, providing support and protection from cracking or damage.

Properly installing corner beads involves applying thin-set mortar to the back of the bead and pressing it into place over the backer board joint. Ensure the bead is straight and level, and allow it to dry completely before applying tiles.

After the corner beads are installed, you can apply thin-set mortar to the back of the tiles and set them in place. Use spacers to ensure even spacing between the tiles and press them firmly into the mortar. Once the tiles are set, allow them to cure for the recommended time before grouting.

When grouting outside corners, use a non-sanded grout that is flexible and resistant to moisture. Apply the grout using a grout float, pressing it into the joints and removing any excess. Allow the grout to cure completely before sealing it with a waterproofing sealer.

By following these essential aspects, you can ensure a durable and waterproof tile installation in outside corners using tile backer board. Remember to use the correct materials, install corner beads properly, and allow for proper curing times to achieve optimal results.
